The simplicity and advantages of the construction will, it isthought, be readily apparent to those skilled in the art to which the invention relates so that further detailed LiGSCIiP'idOH will not be required, but it is to be understood that I do not Wish to be restricted to the precise details of construction herein set forth and, therefore, hold myself entitled to make such changes there from as fairly fall Within the scope of What I claim.

Having described the invention, 1 claim:

A device for the purpose set forth, including a boxing having flared portion. receiving therethrough the spindle end of an axle which is reinovably fixed thereto, a wheel hub arranged over the boxing, keyed thereto and having a flared portion to overlie the flared portion of the boxing, said hub having equidistantly spaced openin therethrough and the boxing having notches uiining with said openings, dogs pivot-ally secured to the hub and having their active ends received through the openings and in the notches of the boxing, spring means influencing the dogs to such position, an annular flexible element passing through the outer ends of the dogs and a rotatable pin through which the flexible element is received, as and for the purpose set forth.

In testimony whereof I aiiix my signature.
